No DVB-T2 support with mygica t230

Hi!

I own 2 dvb tuners. the Astrometa DVB-T2 old one and a new Geniatech Mygica T230.

I am pretty sure that it's T230 because I tried not avoid the T230C model. The item description on Aliexpress says loud and clear "NOT T230C".

Anyway, I plugged it to my raspberry pi 3 with the latest LE image and I only get the tuners: DVB-T,DVB-C,ATSC-C.

All of them are listed as Silicon Labs Si2168.

No DVB-T2. I really want to watch tv in HD so I bought the mygica model especially for that but I can't figure out what's wrong.

I tried removing TVH entirely and start configuring from scratch. didn't work.

I tried to install the image that includes other dvb-drivers but there was no change, but I just installed it I don't know if I need to do anything else after the image installation.

Any Ideas?

It's correct that your tuners are being identified as DVB-T capable. The decoding of DVB-T2 is just a matter of setting up the muxes in the right way. For Germany it's like this: Howto: Setup german DVB-T2 "beta" channels - Tvheadend

Keep in mind that in Germany DVB-T2 is being encoded using HEVC and to decode that you basically need capable hardware that does hardware based HEVC decoding. A Raspi is not powerful enough to decode HEVC streams.

In other countries probably other codecs are being used and a Raspi maybe sufficient.

ok so I scanned for channels but I only found SDTV channels. See in picture.

I live in Israel by the way and I know there supposed to be at least 2 hd channels.

Thank for your help.

oh my god I am so sorry.

The support for HD channels was stopped in israelfor some reason. I wasnt aware of that.

My bad.

Thank you so much for your help I hope it will get fixed soon.

Are you sure the support stopped in Israel?

I'm also using the T230 and can only find channels in 514MHz DVBT. although, it's should be possible in 530MHz DVBT2

Hi guys,

Any tips on how to make the mygica t230 work on raspberry pi 3? For some reason, I can't scan for channels. Get scan failed every time. Using latest LibreElec. I can see the tuner in tvh listed as Silicon Labs Si2168.

I can't scan for channels.

likely a driver problem, try LibreELEC 8.x images for additional dvb drivers if that LE Version works.

I've tried all of them - none work.

I have another dongle (PCTV) that works fine - so this is probably not a configuration issue.

The MyGica T230 dongle was tested on windows machine and works prefect.

Anything else that I can do?
